I believe there exists a hadith from Imam Sadegh (as) talking about the believers not eating and wearing the clothes of the enemies of God Almighty. How can we identify which practices are from the enemies and how can we identify the enemies of God?
Identifying the enemies of Allah (SWT) is based on their conflict with the message of Allah, His Prophets and Ahlul Bayt (AS) who are the real successors of the Prophet Muhammad (SAWA).
The practices which are done by them and known by people as part of the life of the enemies of Allah (SWT) must be avoided.
Wassalam.
